The electric power consumed by an electric kettle is 2000 W. If the voltage being supplied to the kettle increases 4 times and the current flowing through the kettle is decreased by half, what would be the effect on the power consumed by the kettle?
The electric power would double.
The formula of finding electrical power is P=VI. If the voltage increases 4 times and the current flowing through the kettle becomes half then P = (4V)(1/2)I = 2(PI). The electric power of the electric kettle would become double.
